' PAUL BERGEN, or nrcnwoon, WIscoNsrN.

NoN-REFILLABLB CONTAINER.

To all whom/15 may concer/n.'

' Be it knownthat I, 'PAUL BERGEN, a citizen of the United States, and aresident of Richwood, in the county of Dodge and State of lVisconsin,have invented a new and Improved Non-Refillable Container, of which thefollowing is a description. f

- My invention relates to what is generally termed a non-relillablebottle although capable of use in being embodied in other containershaving a neck. The invention particularly relates to a glass container,a portion of the neck of which is adapted to be broken off for gainingaccess to the container, means lbeing provided to prevent the refillingof the container otherwise than by breaking the neck.

The prime object of my invention is to improve the bottle sealing means,whereby various advantages and numerous results are obtained, amongwhich are'the following: The fracture of the bottle neck will berequired to follow predetermined lines, whereby the permanent neckportion will not present a jagged form; the base portion or permanentpart of the neck will have the strength to withstand the forcing'of acork therein 'after the upper portion ofthe neck has been broken of thelocking lingers for locking the y'cap in Vplace are-givenifirm en'-gagement within medium of a metallic bushing provided for the purpose asdistinguished from engagement with shoulders or the like formedintegrally on the inner wall of the neck; the form and arrangement ofthe parts are such to promote simplicity and cheapness of manufacture,as well as convenience in producing the final assemblage.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

the bottle neck through the For the indicated purpose the neck isprovided with a series of recesses 12 between which the neck presentsvertical ribs or beads 13. In the beads l13 horizontal notches 14: areproduced following the general y Patented Apr. 15, 1919. Applicationfiled May 20, 1918. Serial No. 235,679.

rounded lines of the neck, the notches thus serving to vweaken the neckat the beads transversely of said beads. Also, to further determine theline of fracture, I produce shallow horizontal notches 15 in thematerial of the body of the neck 11 at the recesses 12 and in line withthe notches 14. Thus, `the notches 14, 15 make up an annular series, therespective not-ches alternating and the `whole producing a weakenedannular line broken in its continuity only at the sides of each bead 13.

A sealing cap 16 of generally inverted Acup-shape is provided to coverthe top of the neck and extend downward at the outside thereof. The saidcap 16 carries locks ing fingers 17 which depend from the inner side ofthe top lof the cap, four of such ngers being employed in theillustrated form and disposed 90o apart. The fingers 17 are of springmetal and the lower ends 18 thereof are bent outwardly to produce hooks.In order kto give a firm yengagement to the hooked ends of the ngers, Iprovide the 'bottle neck with a bushing 19,the lower edge of which isadapted to be engaged by said hooks. The bushing 19 may be secured inany suitable manner; in the form shown in Fig. 1 the bushing is formedwith a top flange 2O to rest on the bottle neck and below said neckexterior threads are formed on the bushing to engage internal threads onthe bottle neck as indicated at 21. In the form shown in Fig. et theparts are the saine except that an external depending annular flange212' is formed on the outer edge of the top flange 20a-1 and Vhasinternal threads to engage external threads on the bottle neck asindicated at 21b. f

VIn the illustrated construction, the fingers v 17 are permanentlysecured to the cap 16 as follows: Said fingers are formed integral isplaced against the underside of the top of the cap. YAny ou-ter ring 23extends about the head 22 between the same and the Vdepending iiange orskirt of the cap 16 and a second ring 21 is placed against the undersideof the` head 22fwithin the fingers 17.

The cap 1 6 hasa central depending head 25, the Vvbase of which iscontracted to form a .neck25a- With the parts assenibledin the cap 16,Yit -beiiig'understood that; the latter is inverted, molten metal 26ispoured intoV the cap so that the elements 22, 23, 24, a `will be castin said molten met-al and held Y firmly in rigid relation to each otherand rigid'with the cap 16. The inner edge of Y the ring 24 is beveledYas clearly shown, in'

Figs. 1 and 4 to allowa substantialainount of the molten metal 26to-extend about the contracted neck 25?. The knob 25 is accommodated iiia central opening 22a in the head or disk 22. The ribs 13 give theotherwise weakened neck the Vstrength to withstand `end. pressure, 4andthose portions of vsaid ribs below' the notches 1l serve, when the uppersection of tlie'neck Visbroken off, to strengthen the remaining portionagainst the strain of forcing ay cork therein.

I would state in yconclusion tliat'while the illustrated exampleconstitutes a practical embodiment of niyinventio-n, I do not limitmyself strictly to the Vmechanical `details herein illustrated,sincemanifestly the same 'Copies o f this patent'iiiay be obtained for v'tersPatent: with adisk-like head 22, the planes of vwhich. lingers are 'bentdownward,`and said head" can be considerably .varied Without deparl thebushing and having hooked ends adapt- .ed to engage the lower edge ofsaid bushing.
